Problem:
Although powerpoint is widely used in presentation nowadays, black/whiteboards are still not replaceable in some situations. After a long presentation or lecture, it is very possible for the presenter to forget cleaning the board. It is OK if the board is filled with lecture notes. But if the it is confidential information, there will be a problem. Also it is a hassle for professors to clean up the black board every time it is all written.

We would like to design a cheap black/whiteboard cleaning system. By simply waving a hand at a motion sensor mounted beside the blackboard, the brush will go from one side to the pin location you previously put on, and travel back, brushes 2 times in total. More details and functionality are presented below.

Technical Details:
This project will contain three modules:

Brush module: A vertically placed brush pressed to the board.

Motor module: Sliding rail on top and bottom of the board. 2 motors on each side of the rail to drag a wire attached to the rail, to move the brush.

Control module: This module contains three different submodules.
Wave-Clean: An ultrasonic sensor on the side of board, facing upwards. When presenter wave his/her hand at the sensor, board is cleaned.
Leave-Clean: Motion sensors around the room. When no movement for 5mins, clean the board
Partial-Clean: Presenter can put a locating pin on the rail. The brush will then move from the side to the pin, and only cleans part of the board.

It will also include a small rechargeble battery pack to power the motor.

Easy Cube Clock

Featured Project

Today's alarm clock market is full of inexpensive, but hard to use alarm clocks. It is our observation that there is a need for an alarm clock that is easy to set, and turn on and off with little instruction. Imagine an alarm that is set with the intuitive motion of flipping the clock over. When the alarm is on, you can see the alarm time on the top of the clock. To turn off the alarm, you simply flip it over to hide alarm display. Out of sight, out of mind. The front face of the clock will always show the current time, and will flip to the correct orientation.
